FIRE-POT FOR STOVES, FURNACES, &o.

To all wwnt it may concern:

Be it known that I, PHILO P. STEWART, of the city of Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Fire-Pots for Furnaces for Stoves, Heaters, Locomotive and other Engine Furnaces, Sto. 5 and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation thereof, reference being` hereby had to the accompanying drawings, and to the letters of reference marked thereon, which said drawings make a part of this specification.

Like letters represent and refer to like or corresponding parts.

Figure l is a perspective view of the said fire-pot complete and ready to be put into use. Fig. 2 is a vertical section through the center from front to rear of said fire-pot. Fig. 3 is a top view of one of the horizontal sections of which the said firepot is composed, and more fully hereinafter described and set forth. Fig. L.tis a section showing one form of the construction and arrangement of the vertical airchambers in the horizontal sections or layers of which the said fire-pot is composed, and is an enlarged view. Fig. 5 shows the manner of the construction of the said horizontal sections or layers and their relative position as to each other, also, the construction of the vertical and horizontal air-chambers hereinafter described; also, the manner and purpose of introducing` the air into the fire-chamber or chamber of combustion and hereinafter more fully described and set forth.

The nature of my said invention and im provements consist in the construction, arrangement, and employment of horizontal sections or layers for lire-pot for stoves, heaters, furnaces, &c., of cast-iron or other required material, with horizontal air-chambersv between Athe same, communicating with vertical airchambers, and thence with the iire chamber or chambers of combustion,throu gh which and by means of which atmospheric air is admitted to the fire at the sides thereof and above the surface to aid in the combustion of the fuel and in the more perfect consumption or combustion of the smoke and gases evolved from the burning fuel in the said `fire-chamber or firepot in the manner substantially as herein described and set forth.

Having thus described the nature of my said invention and improvements, and to enable others skilled in the art to which my said invention relates to make and use the same, I will here proceed to describe the construction and operation of the same, which is as follows, t0 Wit:

A, Figs, l and 2, is the foundation or base on which I construct my said re-pot, and which surrounds or forms the ash pit or chamber below to receive the ashes and other material falling from the lire-grate at thc bottom of my said fire-pot. This may be of cast-iron, or of stone or other' suitable material, all, however, depending upon the place and purpose when my said f1repot is to be used. Upon the immediate top of this base or foundation I place the first horizontal section or layer, as seen at g, Fig. 2. Upon the top surface of this horizontal section or layer g, I place the second horizontal section or layer j'. Upon this section or layer f, I place the third horizontal section or layer e. Upon this section or layer e, I place the fourth horizontal section or layer cl. Upon this section or layer d, I place the fifth horizontal section or layer c. Upon this section or layer c, I place the sixth horizontal sect-ion or layer b. Upon this section or layer b, I place the seventh horizontal section or layer a, and thus in this manner may be continued the building up of the said lire-pot until the desired height is attained.

This fire-pot, it is manifest, may be built up of less than seven of said horizontal sections or layers, if deemed best so to do. All will, however, depend upon the thickness of each section or layer and the height of the fire-pot. The said sections or layers may be of uniform thickness, or some may be thicker than others, if deemed best so to make them. I prefer, however, to have them of even or uniform thickness. B is the re pot or chamber of combustion. I will now proceed to describe the construction of the said horizontal sections or layers, which is as follows, to wit: Each of said horizontal sections or layers I construct of any size or thickness desired. They may be so constructed as to form a circular, square, or other shaped fire-pot or fire-chamber.

Each of said sections or layers is so constructed as to projectits lower edge over the upper edge of the next section or layer immediately below in the manner substantially as shown at c' and j, Fig. 5. This is for the purpose of preventing the fuel in the lire or conrbustion chamber I) from tilling up the air passages or apertures between the air-chamber K, Fig. 5, and the combustion-chamber D, which said air pass tiges or apertures are shown at the arrows 7L and H, Fig. 5, and there maybe as many such openings or apertures as deemed best.

In the upper surface of each of the said horizontal sections or layers I construct an airchamber, K, in the manner substantially as shown at Fig. 5, which entirely surrounds the said re pot or chamber ot combustion, as seen at-Fig. 3. These I name horizontal air-chambers, and each communicates with the chamber ot combustion D by means of numerous small openings or apertures H and h, Fig. 5, as aforesaid.

I also construct vertical air-chambers G, Fig. 5, which may be ot any size, shape, and number desired. These chambers pass in a vertical direction through the said air-chambers K, same ligure. The air enters these chambers at the bottom or lower part of the said lire-pot, passes up and into the said respective horizontal air-chambers K, same ligures, and thence into the sides of the rein the chamber ot' combustion, through said openings or small apertures, as before de scribed, and for the purpose ot' economy in the fuel by the burning` or consumption of the gases and smoke evolved from the burning i'uel inthe said chamber of combustion. These vertical air-chambers are closed at the upper ends thereof. rIhey may also be constructed as shown at L, Fig. 4C. k, Fig. 5, is a projection upon the under side of each of said sections or layers corresponding toa recess in the next section or layer below, and is for the purpose ot' holding each section or layer in its proper place or position. The projection of the lower part of each ot' said sections or layers, as before described and as fully shown at Fig. 5, protects the said small apertures or openings from becoming clogged up with ashes, cinders, or the like, and thereby preventing' the air from entering said chamber of combustion in the manner and for the purposes aforesaid.

The said lirepot may be applied to any stove, heater, or furnice in any manner and by any suitable means deemed best. i

I claimv rIhe employment of a firepot constructed, arranged, and combined in the manner substantially as and for the purposes herein described and set forth.

In testimony whereof I have 011 this 13th day of February, A. D. 1865, hereunto set my hand.
